Only in one review: Efficiency 84 % (Sealed 36 W 3 A).

Sealed 36 W 3 A: Protection is set correctly and overheating is not an issue, but ripple is high—up to 700–800 mV at low frequency.

12 V 3 A power supply, adapter: After the revisions it runs without overheating even at 3.2 A, with acceptable ripple and electrical safety.
